Summary

TFTPd (tftpd-hpa) is running and default a pxelinux based menu is served. At this point it is possible to:

• Run memtest
• Run debian and ubuntu installers
• Run partedmagic, a nice diskrescue oriented live linux desktop

Config

• Dhcpd (on NURDServices) points to TFTPd (also on NURDServices) using next-server option
• Files are served from /tftpboot on NURDServices

Using HARKboot

• Connect your x86 PC/laptop using UTP (wifi won't work)
• Make sure "boot from LAN" is selected in your computer's BIOS
• Boot up your machine

Installing a new image

• Find your new image (e.g. by browsing to http://cdimages.ubuntu.com/netboot/ )
• Make a new subfolder (e.g. mkdir -p /tftpboot/entries/ubuntu-16.04/amd64)
• Download the image (e.g. cd /tftpboot/entries/ubuntu-16.04/amd64; wget http://archive.ubuntu.com/ubuntu/dists/xenial-updates/main/installer-amd64/current/images/netboot/netboot.tar.gz ; tar --strip-components=3 -xf netboot.tar.gz ./ubuntu-installer/amd64/ ) such that the initrd.gz is in this folder.
• Edit the prompts (...)

Todo

• DOS image
• Netbootstuff on the internet
• Use iPXE or gPXE instead of pxelinux in order to make conditional stuff possible (serve sparc stuff for sun, etc)
